HOME-HAMMOCK MOTOR.

SPECIFICATION forming part of Letters Patent No. 657,893. datediseptember 11, 1900.

Application filed January 6, 1900. Serial No. 640. (No model.)

To @ZZ whom, t nto/.y concern:

Beit known that I, FRANCIS J. LOWE, a citizen of the United States, residing at the city of New York, (Codec Exchange-Building) in the county of New York and State of New York, have invented a new and useful Improvement in Hammock-Swings, of which the following is a specification.

The nature and object of the invention will be fully understood from the following general description and the annexed drawings and will be subsequently pointed out in the claims.

Figure lis a side view of my newly-invented hammock-swing. Fig. Il is an edge view of the same. Figs. III, IV, V, and VI are detail views of various parts more fully hereinafter described.

In the drawings, a designates the supporting-frame of the machine. In this are journaled the shafts p, b, d, e, and k. On the shaft p are mounted the wheel p and the spring p". On the shaft b are mounted the wheels b and o. On the shaft d are mounted the wheels CZ and d. On the shaft e are mounted the Wheels e' and e". On the shaft 7c The spring p is fastened by its inner end to an arbor on the shaft p and by its outer end to the wheel p, near the periphery thereof. The wheel p is mounted loosely on the shaft p. The spring pf is wound up by applying a key or wrench to the square shank on the end'of 4the shaftp. This spring is held wound up by a pawl r, working in the ratchet-wheel q, mounted on shaft p. Both ratchet and pawl are of common and well-known form. The Wheel p' which is loosely mounted on the shaft p, meshes into and drives the wheel b. wheel b' on the same shaft meshes into and drives the wheel d on the shaft d. 'lhe wheel d on the same shaft meshes into and drives the wheel e on the shaft e. The wheel e on this same shaft meshes into and drives the wheel s on tne shaft 7a. The shaft k projects beyond the supporting-frame and is provlded at its outer end with a universaljoint s, by which it is connected to the shaft 7c. The outer end of the shaft 7c is provided with a collar and set-screws e e. The shaft It is hollow, and in itis placed the shaft k", which is movable lengthwise in shaft 7.a and may be their entire length.

The

held in adjustment by set-screw z. Upon the outer end of the shaft 7s is mounted the Wheel t. The bar lis fastened securely and rigidly to the supporting-frame ct. A sleeve constructed with a collar f and a lug w' is adapted' to slip on this bar. The rockerf is formed with a hole o, having an extension o, adapted to slip on the said sleeve. The rocker fis of the form illustrated. It is provided with a series of pins set in a segment of circle, (designated by These pins are all equally distant from the bar Z, and the wheel t meshes into them, as hereinafter described. The socket g on the .rocker f by means of the set-screws g holds the bar h, which reaches downward to and through the block 71,', which is pierced with the set-screw h. At right angles to the seat of the bar h this block 7L is pierced by two channels which are parallel to each other and slightly intersect through ln these channels are placed the bars t' and t', and the parts are so arranged that when the screw h is set up it will bear on both bars t' and il, and they will bear on the bar h, so all four-the block h, the bar h, and the two bars t' and t'*are adjustably and detachably fastened by the setserew h together. At t" the bars t' are bent in a loop to give them greater elasticity, as more fully hereinafter described, all the various parts of my invention to be substantially as illustrated in the drawings.

To use my invention, the back side of the supporting-frame is securely fastened to any convenient and proper support. To this same support and directly under the machine is to be fastened the cords of a hammock, (designated by w.) The sleeve (illustrated in Fig. IV) is put into the hole u of the rocker, passing the lug` w through extension 'U' of said hole. The sleeve is then turned so that the lug w will be at the side of the hole u opposite the extension'o@ The flange f will then prevent the rocker from slipping one Way,and the lug w will prevent it from slipping the other way. The set-screw f" is then put in its place in the lug w. The sleeve, carrying With it the rocker f, is now slipped on the bar l, so that the rocker will hang down below the bar and the set-screw f" will be above the bar. The bars h and t' are adjusted so as to engage the cords of the hammock and se- ICO cured in position by the set-screws h and g. rlhe set-screw f is now set up, Then shaft la", carrying the wheel t', is slipped forward toward the rockerf until the conical end of the shaft la" rests in the'groove of the rocker and the wheel t properly engages the teeth or pins t". The set-screw z is then set up to secu re the shaft 7o" in proper position. Lastly, the spring p is wound up by applying a key or wrench to the square shank on the end of the shaft p. The machine is now ready to operate, and theperson who is to occupy the hammock is put into it, and,lastly,the personl in the hammock or an attendant must give it a start to swing. It will then be found that as the wheel if/ revolves, driven by the train of wheels aforesaid, it will engage the pins t. The conical end ofthe shaft 7c, following the groove o: of the rocker, will always keep the wheel and the pins in mesh. As the wheel cannot move laterally, but the rocker can turn on the sleeve on the bar Z, the wheel willdrive f y actuated substantially as set forth, and the t su pportiug-frame in which they are journaled the rocker past it one way until the wheel has reached the end of the row of pins. Then the shaft 7o moving in the universal joint s and in the guide s and the continued motion of the wheel t carrying the shaft 7c" forward the shaft will follow th'e groove x and the wheel will swing around the end pin and engage the pins on the opposite side. This will cause the rocker to move the other way, and so by the wheel working alternately above and bev low the pins the rocker will be swung steadily to and fro, at the same time carrying with it the bars h t' t', and as one bar t' had been adjusted on one side of the cords of the hammock and the other bar 2' on the other side of the cords so the bars will swing` the hammock back and forth with the cords between them until the resilient force of the spring lo is exhausted. rlhe loops t" are bent in the bars z' so that they will be elastic enough to ease any jar that may be caused by the motion. When the spring has run down, it may be rewound and the process repeated as often as may be desired When the set-screw f is loose, the sleeve and the rocker may be slipped to any desired place on said bar Z or entirely off of it, and so the rocker can be adjusted to the size of any hammock, and ou account of the shafts lo It being telescopic the wheel t may be adjusted to engage the teeth t" of the rocker in any position in which they may be placed.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination with a revoluble shaft,

v supported and actuated 'substantially as hereinbefore set forth, of a bar rigidly fastened to the supporting-frame in which said shaft is journaled, a sleeve upon said bar formed with flange and lug substantially as specified, a rocker, having a hole adapted to said sleeve as set forth and by means of said sleeve and its set-screw mounted adjustably and detachably upon said bar, and formed with a socket, and curving groove and pins, a bar in said socket, a set-screw to bind said bar adjustably in said socket, a block upon said bar pierced with a set-screw for securing said block, to said bar, and spring-bars in said block, said block also pierced with a channel for said bar, and two other channels for spring-bars, spring-bars in said channels adapted to engage the cords of a hammock as set forth, a universal joint on the end of said revoluble shaft, a telescopic shaft attached by said universal joint to said revolu- `ble shaft, a guide to control the motion of .said telescopic shaft, the end of said telesco ic shaft envariuv the groove in said b b b `rocker, and a wheel mounted on said telescopic shaft, engaging the pins of said rocker,

substantially as and for the purpose set forth. 2. The combination with a train of wheels,

of a bar rigidly fastened to said frame, a sleeve upon said bar formed with flange and i lug as specified, a set-screw in said lug, adj justably and detachably attaching said sleeve to said bar, a rockermounted on said sleeve,
